When fighting Dracula at the end of the game, wait to attack him until you turn into a werewolf. Otherwise, he will be invincible. After awhile of using Tojo Blades, you will hear a scream and you will become a werewolf. Later, you will temporarily be Van Helsing. Also, your background will be bluish when you are a werewolf and normal when you are not. Note: Dracula remains normal until attacked; you will be okay until you turn werewolf.
